Cloudbrain is an internet software company, creating fun programs since 2002. We are a group of coders, designers and marketers and know our way around Photoshop, web design and are really good at pointing out what we like and what we don't.
We use 99Designs to think outside the box. We have a lot of graphic design experience and give a lot of feedback.
We are starting a new service that backs up all your music files called:
The name is a play on the phrase "bomb shelter" because the service keeps your songs safe in case of a disaster.
We are looking for a logo for our "SongShelter" service.
1) The design should have both a logo and the text of our name, "SongShelter" but they need to be separate elements - sometimes we will just show the logo without the name (i.e. don't just stylize the name)
2) The logo needs to be icon-like (we will use it for the application icon on a user's desktop). It needs to be highly detailed, 3D and somewhat realistic (just like most official Mac OS X icons). See examples below.
3) The logo needs to be themed around "bomb shelter", "fallout shelter", "bunker", "radiation" etc. It should also incorporate some sort of "music" element (i.e. a music note or speaker or something). Feel free to get creative and have fun. Funny is good. Scary is bad.
UPDATE: Here are more examples:
